ABSTRACT

In this study, the performance analysis of the thermoelectric-solar (TEM-SA) hybrid energy harvesting system is presented. The proposed system is analyzed for continuous and discontinuous load condition and mobile devices as a load. In this feed forward type of controller, Inverse Dynamic Analysis Input Shaper (IDAIS) is introduced to shape the unsteady response behavior to become stable input and is named as Shapeable MPPT (SMPPT). The experimental analysis is done to verify the performance of the new arrangement proposed circuit of HEHS which is used only one MPPT board. An initial test is made in determining which energy-efficient sources are capable to produce the highest output. Then the device that produces the highest output is connected to the new arrangement proposed circuit incorporated SMPPT unit, the converter, and the energy storage. With constant source supply, full charging time obtained for mobile phone is 4 hours and 30 minutes which is equivalent to the charging period using the normal alternating current sources. Greater focus is then given to the charging time for some types of mobile phones that have different battery capacity mAH. From the verification results, it is found that the load that having lowest mAh values steadily able to reach the full charging period faster than the others.

摘要

在本研究中，介绍了热电-太阳能 (TEM-SA) 混合能量收集系统的性能分析。所提出的系统针对连续和不连续负载条件以及作为负载的移动设备进行分析。在这种前馈类型的控制器中，引入了逆动态分析输入整形器 (IDAIS) 以将不稳定响应行为整形为稳定输入，并被命名为可整形 MPPT (SMPPT)。进行实验分析以验证仅使用一块 MPPT 板的 HEHS 新布置建议电路的性能。进行初步测试以确定哪些节能源能够产生最高输出。然后将产生最高输出的设备连接到包含 SMPPT 单元、转换器和能量存储的新安排建议电路。在恒源供电下，手机充满电的时间为4小时30分钟，相当于使用普通交流电源的充电时间。然后更加关注具有不同电池容量mAH的某些类型的移动电话的充电时间。从验证结果可以看出，具有最低 mAh 值的负载能够比其他负载稳定地更快地达到完全充电周期。
